Syntheses of new (CdO)(1-X)(NiO)XZnO nanocomposite system: Preparation, structure, and magnetic properties

This paper presents a new nanocomposite system of (CdO)(1-X)(NiO)XZnO (0≤X≤1 mol). The proposed nanocomposite system is synthesized using a hydrothermal method to experimentally study the structure and magnetic properties of the (CdO)(1-X)(NiO)XZnO (0≤X≤1 mol) system. The formations of the nanocomposite with CdO (face-centered cubic) and ZnO (hexagonal) phases are determined using the X-ray diffraction analysis (XRD) diffractogram and they are confirmed with a high-resolution transmission electron microscope (HRTEM). In our study, we use a Celref Unit-Cell refinement code to determine the crystallization parameters, lattice parameter (a, b and c), bond length (l), cell volume (V) and theoretical density (ρ), while the average crystallite size (Dav), dislocation density (δ), and the microstrain (ɛ) are determined using the Scherrer equation. Additionally, we analyze the magnetization curves and the mass magnetic susceptibility (χmass) of the nanocomposites (CdO)(1-X)(NiO)XZnO system using a Vibrating Sample Magnetometer (VSM). Lastly, the effect of substituting Cd+2 ions by Ni+2 ions on the above properties is discussed.
